"Making Career Readiness Count 3.0" provides an analysis of how the 50 states and the District of Columbia are including and incentivizing measures of career readiness in their new accountability systems under ESSA, as well as an analysis of state-level accountability systems in states with dual systems. This report is the result of a collaboration among Achieve, Advance CTE, the Council of Chief State School Officers (CCSSO), and Education Strategy Group (ESG) and is the third report in a series developed through a longstanding partnership between Achieve and Advance CTE (previous versions were released in 2014 and 2016). The report uses the framework outlined in "Destination Known" to classify states' measures of career readiness within the framework's four categories: Progress Toward Post-High School Credential, Co-Curricular Learning and Leadership Experiences, Assessment of Readiness, and Transitions Beyond High School. The report also includes key themes emerging in career readiness and a detailed state-by-state look at how measures of career readiness are included in each state. [For the 2014 report, see ED547272.
